Time-Dependent Finite Element Analysis in Restrained Concrete: A study on the effect of analysing the combination of hardening processes and external loading on improving the prediction of the development of design stresses

Concrete is widely used in civil engineering and despite its long history, accurate prediction of the hardening process, particularly in partially restrained conditions, remains a challenge. During the hardening of partially restrained concrete, residual stresses occur due to restrained deformations caused by factors such as heating/cooling and...

Early-age Cracking of Concrete: A study into the influence of stress relaxation on early-age cracking of concrete structures under imposed deformations

When hardening concrete is subjected to imposed deformations, stresses maydevelop. If at any point in time this stress exceeds the tensile strength ofthe material, the concrete will crack. Early-age cracking of concretestructures may lead to issues related to durability, serviceability and aesthetics.During hardening of...

Autogenous Shrinkage of Cementitious materials containing BFS

In the Netherlands blast furnace slag (BFS) cement is commonly used. Concretes with this type of cement are known for good durability properties. Where concrete is designed to crack in order to let the incorporated steel reinforcement take over tensile stresses, it is mainly for durability reasons that non-designed cracking of concrete is...
